Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

P.S. Not that I would ever want to put my thumb on the scale of any contest, but I am defending the flat tax in an online debate for U.S. News & World Report with someone who favors the current system. You can cast a vote if you have an opinion on the matter.

P.P.S. Caleb has independently produced a video on the meaning of free enterprise. With politicians acting as if the business community is an ATM machine to finance a bigger welfare state, Caleb’s video puts a human face on what it means to be a risk-taking entrepreneur.

The new budget from the White House contains all sorts of land mines for taxpayers, which is not surprising considering the President wants to extract another $1.3 trillion over the next ten years. While that’s a discouragingly big number, the details are even more frightening. Higher tax rates on investors and entrepreneurs will dampen incentives for productive behavior. Reinstating the death tax is both economically foolish and immoral. And higher taxes on companies almost surely is a recipe for fewer jobs and reduced competitiveness.

The White House is specifically going after companies that compete in foreign markets. Under current law, the “foreign-source” income of multinationals is subject to tax by the IRS even though it already is subject to all applicable tax where it is earned (just as the IRS taxes foreign companies on income they earn in America). But at least companies have the ability to sometimes delay when this double taxation occurs, thanks to a policy known as deferral. The White House thinks that this income should be taxed right away, though, claiming that “…deferring U.S. tax on the income from the investment may cause U.S. businesses to shift their investments and jobs overseas, harming our domestic economy.”

In reality, deferral protects American companies from being put at a competitive disadvantage when competing with companies from other nations. As I explained in this video, this policy protects American jobs. Coincidentally, the American Enterprise Institute just held a conference last month on deferral and related international tax issues. Featuring experts from all viewpoints, there was very little consensus. But almost every participant agreed that higher taxes on multinationals will lead to an exodus of companies, investment, and jobs from America. Obama’s proposal is good news for China, but bad news for America.

After several posts about crazy decisions by the UK government, mostly involving extreme political correctness, it’s time to get back to basics and look at tax policy. A financial services consulting firm in London has just released a survey with the stunning finding that one-fifth of entrepreneurs are thinking of escaping the country because of punitive taxes — particularly the new top tax rate of 50 percent.

The poll of more than 300 entrepreneurs by business advisors Tenon also found that many more may follow in an attempt to escape the 50% rate of income tax, due to be introduced from next April on annual incomes above GBP150,000, with nearly half of the respondents (48%) still deciding what action to take. …Tenon points out that in the last month, high profile names such as the actor Sir Michael Caine and the artist Tracey Emin have threatened to change their tax residency to countries with more favorable tax rates. Popular locations for redomiciling include Monte Carlo, Guernsey, Liechtenstein, and the Cayman Islands. Andy Raynor, Chief Executive of Tenon Group, noted that entrepreneurs are showing their disapproval of the tax measures by “letting their feet do the talking.”

The mayor of London, meanwhile, is much less restrained regarding the foolishness of Gordon Brown’s class-warfare policy. Here’s what he has to say in the Daily Telegraph:

[T]he 50 [percent] tax rate that is beginning to drive these people away is a disaster for this country, and it is a double disaster that no one seems willing to talk about it. When Margaret Thatcher’s government cut the top rate of tax to 40 per cent in 1988, she was completing a series of reforms — beginning with the removal of exchange controls and followed by the Big Bang — that helped to establish London as the greatest financial centre on earth. Britain had been transformed from a sclerotic militant-ridden basket-case to a dynamic enterprise economy, and the capital became a global talent magnet. …So it is utterly tragic, at the end of the first decade of this century, that we are back in the hands of a government whose mindset seems frozen in the wastes of the 1970s.

By the way, I’m not picking on England. America is soon going to be making the same self-destructive mistake. Here’s my video on the broader subject of class-warfare tax policy.

Does anyone think that a huge new entitlement program will lead to lower budget deficits? Sounds implausible, yet proponents of government-run healthcare claim this is the case according to the official estimates from the Congressional Budget Office and Joint Committee on Taxation.

To use a technical phrase, this is hogwash. This new 6-1/2 minute video, narrated by yours truly, gives 12 reasons why Obamacare will lead to higher deficits - including real-world evidence showing how Medicare and Medicaid are much more costly than originally projected.

By the way, this video doesn’t even touch on the mandate issue, which Michael Cannon explains is not being counted in order to make the cost of government-run healthcare less shocking.

The bad news this morning on the impact of both the federal stimulus and the Cash for Clunkers program should not come as a surprise to anyone who has paid attention to the history of government intervention in the economy.

New data that the jobs created by the stimulus have been overstated by thousands is compelling, but it’s really a secondary issue. The primary issue is that the government cannot “create” anything without hurting something else. To “create” jobs, the government must first extract wealth from the economy via taxation, or raise the money by issuing debt. Regardless of whether the burden is borne by present or future taxpayers, the result is the same: job creation and economic growth are inhibited.

At the same time the government is taking undeserved credit for “creating jobs,” a new analysis of the Cash for Clunkers program by Edmunds.com shows that most cars bought with taxpayer help would have been purchased anyhow. The same analysis finds the post-Clunker car sales would have been higher in the absence of the program, which proves that the program merely altered the timing of auto purchases.

Right now businesses and entrepreneurs are hesitant to make investments or add new workers because they’re worried about what Washington’s interventions could mean for their bottom lines. The potential for higher taxes, health care mandates, and costly climate change legislation are all being cited by businesspeople as reasons why further investment or hiring is on hold. Unless this “regime uncertainty” subsides, the U.S. economy could be in for sluggish growth for a long time to come.

There seems to be near universal agreement that the excessive use of debt among both corporations, particularly banks, and households contributed to the severity of the financial crisis. However, other than the occasional refrain that banks should hold more capital, there has been little discussion over why corporations choose to be so highly leveraged in the first place. But then such a discussion might lead us to the all too obvious answer – the federal government, via the tax code, encourages, even heavily subsidizes corporate leverage.

Cato scholar and banking analyst Bert Ely has estimated that the subsides for debt have historically resulted in an after tax cost of debt of 3 to 5 percent, compared to an after tax cost of equity of 12 to 15 percent. With differences of this magnitude, it should not be surprising that financial companies and corporations in general become highly leveraged.

For corporations, this massive difference in cost between debt and equity financing results primary from the ability to deduct interest expenses on debt, while punishing equity due to the double-taxation of dividends along with taxing capital gains.

If we are going to use the tax code to subsidize debt and tax equity, we shouldn’t act surprised when firms load up on the debt and reduce their use of equity – making financial crises all too frequent and severe.

Cato’s tax experts, Chris Edwards and Dan Mitchell, have writtenextensively on international tax competition. Their research shows that countries can help attract investment and spur economic growth by lowering their tax rates.

Could countries employ this same strategy to make their sports teams better?

Real Madrid, one of the most popular and successful soccer teams in the world, recently purchased the rights to two of the sport’s top players. They acquired Kaka, who was named the world’s best soccer player in 2007, from Italian powerhouse, AC Milan. And they lured Cristiano Ronaldo, the world’s top player in 2008, away from Manchester United, the reigning champions of the English Premier League.

There are a number of reasons why Kaka and Ronaldo are moving to Spain, but it’s pretty clear that taxes played a significant role. That’s because in 2005, Spain passed a tax break for foreign workers, including soccer players. This gives Spanish teams a huge advantage in bidding wars with teams from higher-tax countries like Italy and England. To make matters worse, England recently raised its top income tax rate.

“The new tax rate in England is going to make things much harder for English clubs,” noted Jonathan Barnett, a leading sports agent whose clients include Glen Johnson, Ashley Cole and Peter Crouch. “It will hinder the [English] Premier League and help the Spanish league because Spain has big tax discounts for footballers, so there’s an enormous advantage to go there. Someone like Ronaldo could be offered the same money at Real Madrid but be 25% better off.”

Similarly, a frustrated executive from AC Milan blames Kaka’s departure on the Italian tax system: “I repeat, this is all a matter of different types of taxation. If we were a Spanish club, we would have saved €40 million.”
